100mL Pear Shape Tube, 200 Parts

Made to API/ASTM oil testing standards, Robinson’s 100mL 6-inch short cone centrifuge tubes are constructed from clear annealed glass, and feature etched white graduation lines for clear and accurate readings. These 200 part tubes are marked from 0 to 200% to allow direct volume readings from test samples and include extra graduation lines for more precise readings between the major values. Tubes are available with the conventional neck opening to accept a cork style stopper (corks sold separately), or with a threaded neck to take a screw style cap (screw caps included).

As an added option, tubes can come factory verified or third-party certified. Factory verified tubes are accompanied by a certificate of accuracy. Certified tubes are volumetrically checked by an independent third-party laboratory according to API standards and come with a certificate depicting volume corrections at each checkpoint. (additional charges apply)
